NCR Corporation Software Development Engineer interview questions

Talked to NCR at career fair, was then invited for the in person final round. There was a one hour interview where I was asked all about object oriented programming and a few coding problems. Overall, the interview was surprisingly difficult.

Very bad interview experience. First round happened through hacker earth and 2 very easy coding questions plus some mcqs. I was invited for on-site interview at Hyderabad office and was asked to reach the office by 12 pm. and I reached half an hour early and there were other interview candidates as well. Believe it or not, I got to do my first round at 6 PM. THEY MADE ME WAIT FOR SIX HOURS. All the interviews were very easy to be frank if know basic sorting and oops. During the second round, the interviewer was giving me all kinds of red flags indirectly on not to join the company because they work on old tech and there is very little scope of career growth. I think I cleared all the rounds, but I am definitely rejecting the offer because if the terrible experience. Also, the recruiter had no clue on what was happening. I don't want to take her name, but she organized the interviews very poorly.
